BUILDING BLOCK on BRICK.

Application filed November This invention relates to a novel lnl-ildingblock or brick construction designed for use in walls, buildings, pavingor constructions employing building blocks or bricks.

An object of my invention is to produce a building block or brick inwhich a novel form of interlocking construction is employed for thebuilding up and the strengthening of any Structure or paving em loyingthe use of my improved building bloc or brick In its composition, byreason of the yleldlng movements permitted between the interlockedblocks without danger of displacement by the freaks of nature orotherwise.

A further object of my building block or brick is to produce a cheapblock or brick by using certain earths which may by the ar t ofcompression, be produced in large quantitles for use in arid sections ofthe country. 7

These and other objects are attained in my improved and novel buildingblock or brick construction described in the following spec1- ficationand illustrated in the accompanylng drawing, in which Fig. 1 is aperspective view of the upper side of a block embodying my invention.

Fig. 2 is a perspective view showing the under side of the buildingblock shown in Fig. 1.

Fig. 3 is an elevational View upon a reduced scale suggestive of a wallconstructed from the form of building block shown 1n Flgs. 1 and 2.

Fig. 4 is a fragmental perspective view of a l modified form of blockembodying my 1nvention.

Fig. 5 is a perspective view of a mod1fied form of block embodying myinvention.

Fig. 6 is a perspective view showing theupper side of a furthermodification of the block embodying my invention.

' Fig. 7 is a perspective view showmg the under side of thebuilding'block shown in Fi 6.

Fi 8 is a sectional elevational view, upon a re uced scale, of a wallconstructed from the fzorm of building block shown in Figs. 6 and Fig. 9is a view of the outer face, upon a reduced scale, of the wall shown inFlg. 8.

The form of building block shown in Figs. 1 and 2, in its general sizemay be that of the usual building block or brick. However, the upper andunder longitudinal faces, instead of being parallel plane surfaces, areformed 5, 1926. Serial "NO/146.527.

on one face with two humps 24 and 25 which in their nature resembleknobs and are square in formatlon, while the opposite face is formedwith two depressions 26 and 27 of the same shape and size as of thehumps to be used. The humps 5 and 6are joined by slop,- in faces,28' and29 respectively and at the s1 es are sloping faces 30, 31 and 32, 33,while at the ends of the block are sloping faces 34 and 35.

The under face of this form of block is made identical to match theupper face thereof, except that instead of being made anaglyphic infacial formation it is made correspondingly diaglyphic so that thebuilding blocks nest properly and interlock. Because of the formation ofthe block into two square sections of identical size and shape theblocks may be staggered in interlocking relation or may be turned atright angles for bonding purposes and still nest properly.

In Fig. 4 the hump of the form just described has been changed to one ofhemispher-- ical form 36. This, although performing the identicalfunctions of the square form, also acts somewhat as a ball andsocketjoint in the I laylng up of the wall or paving. The underside of thisform of block is diaglyphic to correspond with the anaglyphic sidecontaining the-hemisphere 36.

Fig. 5 shows a further modification which consists of the formation ofa' block having octagonal humps 37 instead of square humps as-in'theform shown in Figs. 1 and 2. This is merely a modification whichperforms in a on similar manner to those already described,

'andis shown principally to illustrate the adaptability of my inventionto many varying forms. r

The form of building block shown in Figs. 6 and 7, in its general sizemaybe that as is found in the usual building block or brick. However,the upper and longitudinal faces, instead of being parallel planesurfaces, are formed in one face with two humps 5 and 6 loo which intheir nature resemble knobs and are square, while the opposite face isformed with two depressions 7 and 8 of the same shape as of the bumpsused. The humps 5 and 6 are joined by sloping faces 9 and 10respectively and at the sides of the building block are sloping faces11, 12 and 13, 14, while at the ends of the building blocks are slopingfaces 15 and 16. As these slOping faces .ap

proach the sides and ends of the block they no tioned.

become arched so that their lines of intersection with the lanes of theends and sides will be curved assliown at 17 to 22 inclusive, while theline of intersection 23 of faces 9 and 10 is also curved. I

The under face of the building block is made identical to match theupper face there- 'of, except that instead of being anaglyphic in facialformation, it is made correspondingly diaglyphic so that the buildingblocks nest properly and interlock. Because of the formation of theblock into two square sections of identical size and shape the blocksmay be staggered in interlocking relation or may be turned at rightangles for bonding purposes and still nest properly as aforemen- Thecurvature of the sloping walls 9 to 16 inclusive form a flat at thepoint of their juncture with humps 5 and 6 so as to function as waterdeflectors which drain water away from the exterior and joints of thewalls water that may seek entrance. Also because of this and-theinterlocking feature, the blocks may be laid up with or without bindingmaterials such as mortar and the like, depending largely upon what usethe building blocks are intended for. 1

When such a building block or brick is incorporated in. wall building orpavement as for example as shown in Fig. 8, the manner in which thebuilding blocks cooperate is shown to be that of an interlock whichproduces increased strength while at the same time permitting of bondingif desired.

Thus by means of these or other possible forms of my invention abuilding'block or brick is obtained in which, whether or not mortar orno binding means is employed the bonding'and interlocking features wi.permit of their use or not depending mainly; upon the employment of theblock and the. purposes of the construction for which it is to be used.

Having thus described my invention what.

I claim is 'A building block or brick comprising a sub stantiallyrectangular formation as to all but two faces, the opposite faces whichconstitute said exception being respectively anaglyptic and diaglyptic.and -du each other, the shape of said anag yptic face consisting of twoelevations spaced apart and from the edges of the facebysurfacesinclin-ed away from the elevations, the shape of the diaglypticface being formed to fit the anaglyptic face. i w
